4.
1. Gephi: Open 4 § From the File menu, select Open and then select the .gdf ﬁle you saved from Netvizz § At ﬁrst it sort of looks like a big hairball, so we’ll change the layout to make some sense of these connections

5.
2. Gephi: Layout 5 § From the Layout module on the left side, choose Force Atlas from the dropdown menu, then click Run à Force Atlas makes the connected nodes attracted to each other and pushes the unconnected nodes apart to create clusters of connections § Click Stop when it seems as if you have some distinct clusters of nodes

6.
3. Gephi: Ranking (Degree) 6 § Choose the Ranking tab in the top left module and choose Degree from the drop-down menu à Degree = number of connections § Hover your mouse over the gradient bar, then double click on each triangle to choose a color for each side of the “range” à Try to use a bright colors for the highest degree so it’s easy to see who’s the most connectedTip: You can click the li.le “Table” icon in § Click Apply to see thethe bo.om le4 of the ranking tab then gradient appliedclick Apply to see a table of degree ﬁgures for your nodes

7.
4. Gephi: Statistics (Betweeness) 7 § Click the Statistics tab in the top right module § Click Run next to Average Path Length § Choose Directed from the pop up menu § Click Close when the graph distance reports pops up (unless you want to save them)

8.
5. Gephi: Rank (Betweeness) 8 § Return to Ranking in the top left module, and click Choose a rank parameter from the drop- down (this resets the options) § Then choose Betweeness Centrality from the same drop- down menu § Click on the icon for Size instead of color this time (icons above drop-down bar) § Set Min Size to 10 and Max Size to 50 à Play around with these numbers depending on the nature of your network § Click Apply to change the node sizes according to their betweeness

9.
6. Gephi: Layout (Betweeness) 9 § To keep the larger nodes from overlapping smaller ones, go to the Layout tab in the left module and check the Adjust by sizes box § Click Run for just a moment (then Stop) so the modules will spread out accordingly

10.
7. Gephi: Labels 10 § Click the bold black T in the toolbar at the bottom of the window to turn labels on § Click the black letter A in the same toolbar to select the Size Mode for the labels, and choose the Node Size option § Use the slider (on the right) to adjust the overall label size to your liking § You can also change the font style by clicking next to the slider (Default for me was Arial Bold)

11.
8. Gephi: Community Detection 11 § Go back to the Statistics tab on the right and click Run next to Modularity § Check Randomize on the popup and click OK à This creates a modularity class value for each node, which we’ll use to colorize the communities § Go to the Partition tab in the top left module and click Refresh arrows to populate list § Choose Modularity Class from the dropdown menu § You can right-click on this box and click Randomize Colors if you don’t like the ones that are there § Click Apply to colorize the detected communities

12.
9. Gephi: Filter 12 § Go to Filters in the top right module and open the Topology folder § Drag the Degree Range ﬁlter to the box below (“Drag ﬁlter here”) § Click on Degree Range to open the Parameters, then edit the degree range settings by clicking on the “0” and changing it according to your network § This option basically removes the “leaves” in the network that are not connected to many other nodes § Since Lars has a pretty connected network, we set the lower range to 5, meaning that it hides all nodes with less than 5 connections § Click Filter to apply

13.
10. Gephi: Label Adjust 13 § The Gephi folks recommended to run a ﬁnal layout adjustment before the export that makes it easier to read the labels. There are two options: § “Label Adjust” works much the same as the size adjustment, moving the nodes so the labels are readable § There is an additional plugin you can add called “Noverlap” that also helps to solve the clutter problem (See result on ﬁnal page)

14.
11. Gephi: Preview 14 § At the very top left, click on the Preview tab § Under Node, check the box that says Show Labels. § Click Refresh at the bottom, then set the Label Font under the Nodes section accordingly § Play around with other Preview options until you like the graph you’re looking at! Don’t forget to Refresh after changes.

15.
12. Gephi: Export! 15 § Choose to export (at the bottom left) in either SVG or PDF, and voila! You have visualized your Facebook network community clusters!
